What are the security services PKI provides?
PKI brings to the electronic world the security and confidentiality features provided by the physical documents, hand-written signatures, sealed envelopes and established trust relationships of traditional, paper-based transactions. These features are: Confidentiality: Ensures than only intended recipients can read files. Data Integrity: Ensures that files cannot be changed without detection. Authentication: Ensures that participants in an electronic transaction are who they claim to be. Non-repudiation: Prevents participants from denying involvement in an electronic transaction.
